1GB RAM is really light on for ZFS and there are some known ARC issues
in 8.1 that can lead to free memory starvation. The most obvious
indicator of this issue is that "free" memory reported by "top" OR
"systat -v" drops _very_ low although there is plenty of "cache" and
If you can't update to 8-stable, try changing arc_memory_throttle()
uint64_t available_memory = ptoa((uintmax_t)cnt.v_free_count
uint64_t available_memory = ptoa((uintmax_t)cnt.v_free_count);
at the top of the function. This fixes the worst bug but there are
lots of other fixes if you upgrade.
